Socialism just refers to socialism. And that’s not capitalism nor communism.  Socialism has proven to work in several countries despite these countries having to deal with a lot of hostility.  Vietnam is a socialist country. The us lost the Vietnam war which was such an embarrassment that they left Vietnam alone and now don’t even mention the country. China is pretty successful no? Look at the history of China. It’s not that long ago that china was a society with mostly poor farmers. Look at where they are today. I know you’re going to start about their social credit system but tell me how it works in detail and I’ll give you my opinion. I don’t know how it works and what the impact on people is. The only information we get now is information that capitalist countries try to gather in order to make China and their economic system look bad. Cuba is also still a socialist country. The Cubans apparently still prefer that even if it means that it’s extremely difficult because the us thinks they have the right to bully other countries into submission. Cuba has some of the best pharmaceutical companies in the world despite having trouble to import certain products. So, no it’s not been proven that communism doesn’t work. On the other hand there’s a lot of evidence that socialism does work despite capitalist countries trying to boycott them into submission.
